Title: Optical modulator having optical isolator function
Inventor: ODA HITOSHI
IPC: G02B27/28
Filed: 1990-08-09
Abstract: PURPOSE:To obtain an optical isolator function without obtaining phase matching and to allow optical modulation simply by modulation of a voltage while a magnetic field is held constant by utilizing the mode conversion by an electrooptical effect and magneto-optical effect to provide the optical isolator function and an optical modulation function in combination in the waveguide of a magnetic semiconductor. CONSTITUTION:This optional modulator has the waveguide consisting of the magnetic semiconductor, such as CdMnTe, and executes the optical isolator function by simultaneously applying the modulated electric field and the specified magnetic field to this waveguide to induce the mode conversion between orthogonal modes, such as TE light and TM light, within the same region by the electrooptical effect and magneto-optical effect, thereby compensating the degradation in the mode conversion efficiency by the phase mismatching. The optical modulation function is executed by controlling the electric field. The problem of the phase mismatching in the integrated type optical isolator is solved in this way and the optical modulator having the optical isolator function having the constitution to allow the optical modulation is simultaneously obtd.
